Valid comments BUT - the goal of a logline isn't to tell the whole story but to just to give the hook, the reason to watch it, to suggest the genre it is in, and what the thrust of the story will be. So in my logline - the genre is suggested - "spaceship", "sabotage", "killing", "survive". My genre is sci-fi thriller [with horror elements]. I think there's enough implied there to suggest that. Anyone who guessed horror or thriller is at least in the right ballpark. So obviously, it's not a romantic comedy or a straight up action flick.
The timelock is the oxygen running out, otherwise Frances Cho could take her idle time to find the thing killing the sleepers [the sleeping crew]. The antagonists are the saboteur, and the thing killing the sleepers. The oxygen deprivation IS NOT what sustains the film but it raises the stakes - what really drives the story engine is WHAT is killing the sleepers, and the suspense is whether Cho will discover it before she too becomes a victim.
I remember reading an article on how lack of oxygen causes micro-sleeps, loss of consciousness, delirium, whereas insomnia causes lack of focus, awareness and delirium. Recently after several days of insomnia followed by sleep apnea, where I had trouble functioning, a story idea manifested : I thought what if you were in a situation where you had to be very focused, and had to stay awake, when an environmental factor was threatening to put you to sleep. Lack of sleep threatens your focus but you don't dare sleep even though you crave it like heroin. Because when sleep means death - that would be a very dangerous situation indeed...
I DO appreciate the feedback. And I will rework the logline. Probably need to rework the synopsis too :)
Haven't seen Pandorum, will have to check it out.
BTW - I got the film title into the logline which is a quirk of mine.
Nick, that's a good point . And I have worked out a reason. But that's something to go in the synopsis, can't fit it in the logline. Still will revisit that too, otherwise it looks like a plothole.
